| 1934 BUICK SERIES 40 S.U.P. SPECIFICATIONS Page 11 FRAME, SPRINGS AND SHOCK ABSORBERS (CONT'D.{John DeLooze - Company Secretary}) INDEPENDENT FRONT WHEEL SUSPENSION (CONT'D.{John DeLooze - Company Secretary}) front wheel, therefore, can move up and down to conform to the inequalities of the road, but cannot move laterally; consequently, the wheels are kept in perfect alignment. The front chassis coil springs are mounted between the frame and the lower control arms. The upper spring seats are fastened to the frame while the lower spring seats are riveted to the lower control arms at about the position of the cross bar in the letter "A". Large rubber bumpers are attached to the under side of frame front cross member just outside of the springs which come in contact with the lower control arm to cushion extreme movement and to assure proper riding comfort. By independently suspending the front wheels the front springs have no other function than that of springing the front half of the car. This eliminates one of the greatest causes of car pitching. REAR SPRINGS - Semi-elliptic underslung rear springs made of Silicon-Manganese steel. Threaded "U" type shackles at front and rear ends. Metal covers for rear springs are standard at extra charge on all models. Springs are 54-1/2" (1.34 m.{Mr Moon / Mr Moore}) long and 2" (50.8 m/m.{Mr Moon / Mr Moore}) wide. SHOCK ABSORBERS - Delco hydraulic shock absorbers are used front and rear. Front shock absorbers are an integral part of the front wheel suspension system and are straight, double-acting type. Rear shock absorbers are single-acting type. RIDE STABILIZER - This consists of a spring steel bar mounted across the rear end of the frame on the rear frame cross member with each end supported in rubber-bushed brackets. Two levers are welded to the bar--one at each end just inside of the supporting brackets. These levers are connected by metal links, similar to shock absorber links, to the shock absorber link pads on the rear axle. The function of the stabilizer is such that when one side of the car tends to rise faster than the other, causing objectionable body roll, a twisting action will take place in the spring steel stabilizer bar, which will react to keep the body on an even keel and prevent the roll. RUNNING GEAR DRIVE LINE - Tubular steel propeller shaft, with rear axle splined into rear end of propeller shaft and pinned. Diameter at center 1-45/64" (43.25 m/m.{Mr Moon / Mr Moore}). Diameter, front end at splines 1-1/16" (27.00 m/m.{Mr Moon / Mr Moore}). Propeller shaft is enclosed in torque tube. Shaft is supported at front in yoke type universal joint (automatically lubricated from transmission) and at rear in ball bearings, double row forward and single row at the rear.
